Workspace/interface turned white, it will not change back to grey in preferences interface panel.

[wroblinski]

In Illustrator (most recent up to date version), I did a shortcut and accidentally turned my workspace to white.  I went to preferences ->user interface ->brightness and changed the color.  It changes the interface except for the workspace color, it remains white. However; if I open a new document it does change to the appropriate color.  I just don't want to copy and paste all my work to a new document.  This happened at work on a PC. When I brought the file home I opened it on a IMAC with the same issue.

Try the toggle for Overview Preview which is Cmd-Opt-Shift-Y. Here are two views one with it on and one with it off.

I tried all preview modes with no success, stays white.  I think I'll just copy work into new document.   Really strange.

Thank you! Turning off the overprint preview worked for me. 

[phrosneras]

same happened to me just now. it is not the user interface setting, because that is still set to grey. i dont understand this!? would love to know the reason.

[Thiha26777085yxgw]

I tried Command+Shift+H and worked for me. Try it out.

[Valentino5CC8]

It works! Thank you.

I just had this problem and I was able to solve it by toggling hide artboards with command + shift + H.

[Dinesh_dk]

Thanks a lot MAN!!!!!!!

[wanderella_vlogs]

It happened to me just now. Thanks for this. It worked! 

[Alaina5C08]

Please help! I tried ctrl+shift +H and I tried clicking pixel preview, and overprint preview.  Is there any other reason it could be locked in this mode?  I can't see half of my artwork now.

View > Show Artboards?

[Phase9]

Control click (Mac) and choose dark grey or whatever color you prefer

[Levi5E8C]

CMD + Shift + H or View > Hide Artboards

All that this feature does is hide all the artboards and makes the background white. It's a useless feature for 99% of people. Go to Edit > Keyboard shortcuts to disable this.

A solution if none of those options work is tho check the resolution of your project if its has been changed to a larger width/height zoom out of your project to see the edges and see if that's the problem. If that's the issue you then go to file new find the resolution of the current project ur working on open new project then close and reopen ur previous file it will go back to normal
